2013 GMC Sierra 3500HD
Tried searching through the threads but couldn't quite find the answer. I have a 2013 GMC Sierra 3500HD that I installed a DPF Delete exhaust and tuned with EFI live from REDACTED. No errors during the tuning, but tried to start it and it cranked but doesn't start. I am getting a P2294 error: fuel pressure regulator 2 control circuit. I followed the install instructions but saw on another post that the wires in the ECM plug being installed incorrectly is 99% of the problem... so should I try and switch them?
